Low-energy electrons are ubiquitous in nature and play an important role in natural phenomena as well as many potential and current industrial processes. Authored by 16 active researchers, this book describes the fundamental characteristics of low-energy electron–molecule interactions and their role in different fields of science and technology, including plasma processing, nanotechnology, and health care, as well as astro- and atmospheric physics and chemistry. The book is packed with illustrative examples, from both fundamental and application sides, features about 130 figures, and lists over 800 references. It may serve as an advanced graduate-level study course material where selected chapters can be used either individually or in combination as a basis to highlight and study specific aspects of low-energy electron–molecule interactions. It is also directed at researchers in the fields of plasma physics, nanotechnology, and radiation damage to biologically relevant material (such as in cancer therapy), especially those with an interest in high-energy-radiation-induced processes, from both an experimental and a theoretical point of view.
The authors have studied the B{sup ±} → J/[psi][pi]{sup ±} and B{sup ±} → J/[psi]K{sup ±} decays using a 20.7 fb−1 data set collected with the BABAR detector. They observe a signal of 51 ± 10 B{sup ±} → J/[psi][pi]{sup ±} events and determine the ratio [Beta]({sup {+-}} → J/[psi][pi]{sup {+-}})/[Beta](B{sup {+-}} → J/[psi]K{sup {+-}}) to be [3.91 {+-} 0.78(stat.) {+-} 0.19(syst.)]%. The CP-violating charge asymmetries for the B{sup {+-}} → J/[psi][pi]{sup {+-}} and B{sup {+-}} → J/[psi]{sup {+-}}K{sup {+-}} decays are determined to be [Alpha]{sub {pi}} = 0.01 {+-} 0.22(stat.) {+-} 0.01(syst.) and [Alpha]{sub K} = 0.003 {+-} 0.030(stat.) {+-} 0.004(syst.).
